Binding Listbox to List<object> in WinForms

What's the simplest way to bind a Listbox to a List of objects i开发者_如何学Gon Windows Forms?

You're looking for the DataSource property:

List<SomeType> someList = ...;
myListBox.DataSource = someList;

You should also set the DisplayMember property to the name of a property in the object that you want the listbox to display. If you don't, it will call ToString().

Binding a System.Windows.Forms.Listbox Control to a list of objects (here of type dynamic)

List<dynamic> dynList = new List<dynamic>() { 
            new {Id = 1, Name = "Elevator", Company="Vertical Pop" },
            new {Id = 2, Name = "Stairs", Company="Fitness" }
};

listBox.DataSource = dynList; 
listBox.DisplayMember = "Name";
listBox.ValueMember = "Id";

Pretending you are displaying a list of customer objects with "customerName" and "customerId" properties:

listBox.DataSource = customerListObject;
listBox.DataTextField = "customerName";
listBox.DataValueField = "customerId";
listBox.DataBind();

Edit: I know this works in asp.net - if you are doing a winforms app, it should be pretty similar (I hope...)

Granted, this isn't going to provide you anything truly meaningful unless the objects have properly overriden ToString() (or you're not really working with a generic list of objects and can bind to specific fields):

List<object> objList = new List<object>();

// Fill the list

someListBox.DataSource = objList;

---

ListBox1.DataSource = CreateDataSource();
ListBox1.DataTextField = "FieldProperty";
ListBox1.DataValueField = "ValueProperty";

Please refer to this article for detailed examples.

I haven 't seen it here so i post it because for me is the best way in winforms:

    List<object> objList = new List<object>();

    listBox.DataSource = objList ;

    listBox.Refresh();
    listBox.Update();            

---

There are two main routes here:

1: listBox1.DataSource = yourList;

Do any manipulation (Add/Delete) to yourList and Rebind.
Set DisplayMember and ValueMember to control what is shown.

2: listBox1.Items.AddRange(yourList.ToArray());

(or use a for-loop to do Items.Add(...))

You can control Display by overloading ToString() of the list objects or by implementing the listBox1.Format event.

For a UWP app:

XAML

<ListBox x:Name="List" DisplayMemberPath="Source" ItemsSource="{x:Bind Results}"/>

C#

public ObservableCollection<Type> Results
